The 8 Most Terrifying Diets in the Animal Kingdom

#4. Dracula Ants Are Worse Than Vampires ...

Your typical colony of ants is literally one big, happy family. Unless, of course, we're dealing with the Madagascan genus Adetomyrma, who in any other country would have insect social services busting down their doors. They would be like, ladybugs or something, with little warrants written on buttercup petals.

Members of Adetomyrma are also known as Dracula ants and have been called a "missing link" between ants and their close cousins, the wasps. To other insects, this is like being chased by the missing link between wolves and grizzly bears. You can already tell this only gets more horrible.

Not only do these unholy ant/wasp monstrosities murder you and feed you to their children, they then slice their own children open and suck your liquefied remains right back out of their guts. If a species that eats its own kids makes you think evolution forgot to carry the 1 at some point, then don't worry -- like their namesake, Dracula ants drink just enough blood to keep their victims alive and wriggling, to eventually turn into vampires themselves and continue the cycle of abuse.

Scientists call it "non-destructive cannibalism," but we like to call it "evidence that hell is right here on Earth and it's called Madagascar."

#3. ... And So Is the Vampire Finch

Getting stranded on a deserted island can lead to some pretty desperate behavior. Grown men talk to volleyballs, children worship dead pigs, and cute little Tweetie birds mutate into demonic ghouls.

And the worst version of Hamlet ever filmed.

On four of the Galapagos islands, the sharp-beaked ground finch leads a fairly normal little birdy life of eating bugs all day, but on the two barren, rocky islands of Darwin and Wolf, the same finches have diverged into a ghastly subspecies nicknamed the vampire finch, which wields razor-sharp peckers to feast on boobies (we're still talking about birds).

Vampire finches depend on fresh blood for protein and moisture during long droughts, and the boobies have so adapted to this horror that they barely even give a shit when they start getting beak-stabbed by the blood drinkers. The finches, you see, are really just the Biff Tannens of the bird world, and all the other animals have just had to learn to cope with the assholes.

"Butthead."

When they're not actually pecking holes in other animals, the vampire finches supplement their diet by eating bird poop, as well as pecking the feathers off booby chicks and even pushing booby eggs out of their nests to smash them on rocks. They probably also trash hotel rooms and steal candy from babies.

#2. Beetles That Eat Unborn Snakes

The life of a burying beetle is just marginally more romantic than that of those beetles that eat only poop. A freshly mated pair of burying beetles will actually bury an entire tiny animal corpse underground in one night, and the female spends the rest of her life chewing up rotten meat for her larvae. It's pretty goth, though one species has decided that it wasn't nearly creepy enough.

Nicrophorus pustulatus engages in the "normal" corpse-burying ritual of its cousins, but whenever possible, it prefers to raise its young on a wholesome diet of embryonic snakes. If she can find a snake nest with eggs, the mommy beetle lays her own eggs near them, and the larvae tunnel into the unborn reptiles, eat them alive and use the eggshells as their own protective nursery. We're pretty sure there's a horror movie somewhere that tried to use a scaled-up version of this plot but was canned for being way, way too horrible.

This kind of predatory stealth abortion makes the female pustulatus what is commonly known as "a psychotic bitch," or in scientific terminology, a "brood parasitoid." And while it's a tactic shared by many other insects, this is the first known case of an insect parasitizing the brood of a vertebrate. And in the never-ending horror show that is the animal kingdom, we can only assume that snakes are just the beginning.

"We'll be up in yo' uterus next."

#1. Osedax Worms Eat Whale Bones (From the Inside)

In case you haven't heard, whales are big. The carcass of a whale weighs over 200 tons and takes months or even years to completely decompose. In the perpetual, freezing blackness of the deep sea abyss, a whale dying is like a zeppelin full of Big Macs crashing over Ethiopia. Entire ecosystems have evolved for the singular purpose of making sure no part of that whale goes to waste, not even its bones.

You might even call it a whale of a feast.

Forming over a whale corpse into what looks like pink fuzz are the countless tentacles of Osedax mucofloris, a relative of worms and leeches whose Latin name translates as "bone-eating snot-flower." We're not kidding.

Their microscopic eggs drift like spores in the deep ocean, lying dormant until the day they bump into recently exposed whale bone. On contact with the gigantic skeleton, they take root like plants, drilling into the bone with a network of fleshy tendrils.

Completely lacking mouths or digestive tracts, the worms depend on symbiotic bacteria to break down the fatty oils contained within bone, so technically, they don't so much eat bone as eat the poop of something inside of them that eats bone. That's right: Nature found a way to make the bone-eating process even more disturbing.
